As he considers running for president, Joe Biden is talking with friends and longtime supporters about whether, at 76, he’s too old to seek the White House, according to several sources who have spoken with the former Democratic vice president.

One option that has been floated, according to a source with knowledge of the talks, is outgoing Texas Rep. Beto O’Rourke, who at 46 has become the subject of intense 2020 speculation after nearly beating GOP Sen. Ted Cruz.
